Manufacture of roller-blinds for vehicles

Abstract

A process for producing roller blinds includes defining a plurality of shapes for the completed roller blind in a continuous material band. The band has a uniform width and edges of the roller blind are defined between the longitudinal edges of the material band. Separating strips are defined in the material band between adjacent edges of the devices. The individual devices are removed from the continuous material band by separating the material band along the separating strips.

What is claimed is:  
     
       1. A roller blind comprising: 
       a fabric comprising a reinforced edge formed by at least one of a warp or a weft thread;  
       at least one tubular pocket adapted for receiving a rod, said tubular pocket having a first pocket side comprised of substantially about half of the fabric warp threads, and a second pocket side comprised of substantially about half of the fabric warp thread, wherein a fabric band on either side of said pocket comprises 100 percent of the warp threads.  
     
     
       2. The roller blind according to  claim 1  wherein the tubular pocket engages a rod, said rod defining an indentation extending over its length, the rod further defining a series of projections along an opening of the indentation. 
     
     
       3. The roller blind according to  claim 2  wherein said rod is further adapted for receiving an insert, the insert extending along a first side into a central recess defined by said indentation, said insert adapted for receiving along a second side an expander pressed into the central recess. 
     
     
       4. A roller blind comprising: 
       a fabric having a reinforced edge, said fabric further comprising a pocket having a first opening and second opening, said first and said second openings separated by an uninterrupted portion of fabric;  
       said first opening and said second opening each defined within said fabric by removal of a portion of warp threads from a surface of the fabric, said removed portion of warp threads substantially free of a weft insert.  
     
     
       5. The window shade according to  claim 4  wherein said first opening and said second opening are each adapted for receiving therein respective ends of a rod. 
     
     
       6. The roller blind according to  claim 5  wherein a rod engages a plurality of clips in a region opposite said uninterrupted portion of fabric, said plurality of clips adapted for engaging a window shade guide rail. 
     
     
       7. A roller blind device comprising a reinforced edge defining the shape of the roller blind article said reinforced edge continuously produced in a band of material of uniform width, the single roller blind articles individually removable by separation means seaming the finished articles. 
     
     
       8. A roller blind device according to  claim 7  wherein the reinforced edge defining the shape of said roller blind article is made by an appropriate thread binding. 
     
     
       9. The roller blind device according to  claim 7  wherein the reinforced edge defining the shape of said roller blind article is made by a synthetic thread melted by heat treatment. 
     
     
       10. The roller blind device according to  claim 7  wherein said separation means further defines at least one separation strip. 
     
     
       11. The roller blind device according to  claim 7  wherein said separation means is a separation row. 
     
     
       12. The roller blind device according to  claim 7  wherein said roller blind device further comprises at least one tubular pocket adapted for receiving a rod. 
     
     
       13. A roller blind prepared by a process comprising the steps of: 
       providing a continuous material band having a uniform width defining a plurality of shapes for the roller blinds and said continuous material band having a uniform width by defining edges of the roller blinds between longitudinal edge areas of the material bands;  
       providing separating strips in the material band between adjacent edges of the roller blinds; and,  
       removing the individual roller blinds from the continuous material band by separating the material band along the separating strips.  
     
     
       14. The roller blind device according to  claim 13  wherein said process further comprises providing a thread binding to the edges of the roller blinds in the material band prior to the step of separating the individual roller blinds along the separating strips. 
     
     
       15. A roller blind according to claims  13  wherein said step or providing separating strips in the material band further comprises the additional step of reinforcing the edges of the roller blinds in the material band prior to separating the individual roller blinds along the separating strips. 
     
     
       16. The roller blind according to  claim 15  wherein said reinforcing further comprises placing a thread having a lower melting point along the edges such that subsequent heating of the edges causes the lower melting point thread to melt and seal the edges. 
     
     
       17. The roller blind according to  claim 13  wherein said process further comprises the step of providing a separating row in the material band between each of the roller blinds and the respective longitudinal edge areas. 
     
     
       18. The roller blind according to  claim 13  wherein said step of providing a continuous material band further comprises providing a woven material band. 
     
     
       19. A roller blind prepared by a process comprising the steps of: 
       providing a continuous material band having a uniform width defining a plurality of shapes for a plurality of individual roller blinds and said continuous material band having a uniform width by defining edges of the roller blinds between longitudinal edge areas of the material band;  
       providing separating strips in the material band between adjacent edges of the roller blinds;  
       defining a tubular pocket in the material band along at least one edge of the roller blinds; and,  
       wherein said individual roller blinds are removable from the continuous material band.  
     
     
       20. A roller blind according to  claim 19  wherein said individual roller blinds are removed from the material band.
